Description

Technical Field

[0001] The utility model relates to the technical field of waste gas collection, in particular to a double-flip type suction hood used for collecting waste gas from a die-casting machine. Background Art

[0002] During the production of non-ferrous and ferrous metal castings, metal smelting, casting injection, lubricant spraying, and mold release agent spraying will generate water mist, dust, oil mist, mold release agent mist, smoke and other organized or unorganized harmful waste gases. These waste gases contain various metal oxides and non-metal oxides, and may also contain harmful substances. If they are discharged directly without treatment, they will pollute the environment and have an impact on human health. In order to meet environmental protection requirements, achieve emission standards, purify workshop air, improve workshop environment, and prevent damage to workers' occupational health and the occurrence of occupational diseases, it is necessary to effectively purify the waste gases generated by the die-casting process.

[0003] Currently, most domestic foundries fail to effectively treat and purify hazardous gases such as smoke, fumes, and dust generated in their workshops. Some resort to direct discharge, completely failing to meet environmental and occupational health requirements. A very small number of foundries implement purification processes, but the common approach is to centrally treat the air by connecting individual pieces of equipment within the workshop via pipes. This involves creating a hood on each piece of equipment in the workshop, connecting each hood to a main pipeline, which then flows into an outdoor dust removal tower.

[0004] In the Chinese patent publication number CN110665323B, a waste gas purification system suitable for a die-casting machine is proposed. After studying the existing technology and the above patent, it is found that the existing waste gas collection cover of the die-casting machine is not flexible enough to use. The collection cover needs to be removed when repairing and replacing the mold, which is not convenient to use. Therefore, the utility model proposes a double-flip suction cover for collecting waste gas from the die-casting machine. Utility Model Content
